Title: Secondary heat transfer circuits for nuclear power plant
IPC: G21D5/08
Filed: 1976-08-16
Abstract: 1516254 Steam generators COMMISSARIAT A L'ENERGIE ATOMIQUE 16 Aug 1976 [22 Aug 1975] 33992/76 Heading F4A [Also in Division G6] A secondary heat transfer circuit 1 (Fig. 1) of a nuclear power plant (especially one including a liquid sodium cooled fast reactor) comprises a steam generator 2 having a central duct 11 by which sodium passes to a pump 13 for return to primary heat exchangers 3, 4 associated with the reactor. Relatively hot sodium from the primary heat exchangers 3, 4 enters the steam generator casing 7 and passes around steam-generating and superheating tubes 8 prior to entering the central duct 11. This duct 11 has a two-stage pump mounted inside it in one embodiment (Fig. 5, not shown) or above it in other embodiments. The steam generator, pump, attendant pipework and ancillary apparatus may be housed in a sealed cell (20) (Fig. 4; not shown) integral with the reactor building (21). An outlet from the steam generator base is sealed by a rupturable membrane (7a). In the event of a pressure rise due to a sodium-water reaction in the steam generator, the membrane is broken and the steam generator drains to a dump tank (29) having an associated hydrogen vent stack (30, 30a).

Abstract: 393,626. Winches. SWINSON, E. A. S., 73, Upper Newtownards Road, Belfast. Dec. 8, 1931, No. 34013. [Class 78 (v).] In winch for use on fishing vessels drums wd for trawling, drums sb for seining, and a rope coiler rc are mounted on a turntable bp through which passes centrally a driving shaft. A worm w can be connected to the shaft by a clutch c controlled by a hand-wheel cw and engages a worm wheel ww on a horizontal shaft hs which is connected by gearing g to the main shaft ms. The drums wd are loose on the shaft ms, but can be secured thereto by clutches dc. The trawl net warps are guided on to these drums during winding by a frame which is guided horizontally and operated through a rack r by a pinion p rotated by a hand-wheel hw. When the winch is used for seining, the clutches dc, are released, and the drums wd held by brakes actuated by handwheels bw. The drums sb are fast on the main shaft. Each coiling head of the rope coiler may be driven by chain gearing from its own barrel, or both heads may be mounted on a single shaft which is driven by chain gearing cd from the shaft ms. A clutch is provided in order that this latter drive may be disconnected when trawling.

Abstract: 1,140,609. Pressure vessel closures. RHEINSTAHL HUTTENWERKE A.G. and W. WENZEL. 29 July, 1966 [2 Aug., 1965], No. 34097/66. Heading F2P. A pressure vessel closure arrangement comprises a flange 7 of a cover having a sealing engagement with a flange 2 of the vessel 1, a cylindrical collar 4 secured to the vessel flange and provided with heating arrangement 3 to produce axial expansion of the collar, and thrust transmitting elements 6 inclined to the vessel axis and disposed between a flange ring 5, which is secured to the collar, and the cover flange. The heating arrangement comprises two separate induction coils, each capable of producing the necessary expansion of the collar. To effect the closure, the cover is laid on the vessel and the cylindrical collar inductively heated by the coils. Expansion of the collar permits the elements 6 to be positioned between the flange ring and cover flange. Subsequent cooling secures the cover to the vessel. The cooling may be accelerated by blowing air between annular gaps 11 and 12 through ports 10 and 9 respectively. The inclination of the elements 6 is arranged relative to the centres of areas of flange ring and cover flange cross sections so that the induced moments acting on the flange ring and cover flange are minimized.
